ILLUMINATED SIGN.

To all whom it rnay concern:

Be it knownthat I, CHARLES L. CARTER, a

citizen of the United States, residing at Marionfin the county of Grant, State of Indiana, have inventedcertain new and 'useful Improvements in Illuminated Signs; and I do hereby declare "the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertain's to make and use the same. I

The invention relates to illuminating signs particularly to the class of signs of materia and formed of transparent letters,

- combined with incandescent'bulbs mounted within the casing.

.Signs of this general type, as ordinarily constructed, have the ob ection of displaying certain letters closely adjacent and. in front of the lights with .more brilliancy than'those remote from the lights.

- The inventiontherefore aims primarily, to

which reference is had to the aocom anying drawings, forming a art of this speci cation, hke characters of re erence designating simi-, lar parts, throughout .the 83781 3.]. views,

Figure 1 is a front elevation of a sign embodying the characteristics of the resent invention. Fig. 2 is a horizonta sectional view thereof. Fig. 3- is a detailed view show ing a fragment of one of the walls of the easing, with a lens opening therein. Fig. 4 is a section on the line 4-4 of Fig. 2. Fig. 5 is a her of forming the lens openings in the wall detailed perspective view showin the'man-- of the casing. 0 V

In the accompanying ;drawings, the numeral 5 designates a rectangular opaque cas-j ing provided at relativel opposite corners with vertical posts 6 an 7, which aredisposed on the interior thereof. The said cas-- Specification of Letters Patent. application filed Deeember 19, 1907. Serial No. 407,214.

ing 5 has its-oppositely located side walls provided with lens openings 8, which are arranged in series to form letters or other symbols or. signs. The said side walls are slitted as at 9 at one side of each of the openings 8, and the material on each side of the slits 9 is bent in opposite directions to afford. in-.

wardly pro ecting spurs 10 and outwardly projecting spurs 11. nated by the numeral 12 andareformed Wit threaded angular flanges 13 which are engaged in the openings 8 and which-are held in such relation by the engagement of the spurs 10 and 11 in the rooves between the t reads, the provision 0 said spurs aflording a two-point engagin surface.

The incandescent ights or lamps are designated by the numeral 14, and are mounted in pluralities upon, the posts '6, the said lights being located on opposite sides and at olpposite ends of the casing 5. Secured to t e posts 7 are vertically dis osed shield.

plates 15 formingreflectors w ich are ex tended dia onally of the casing 5 and which are isp'os ed in acommon diagonal plane, so as not to interfere with the angles of reflectionof the light rays. These plates 15 are located 0 posite to each respective seriesof lens, and are adapted to distribute or reflect a light to the opposite side walls of the casing 5, and, which plates are of such The lenses are desi length as. to allow for var ing angles of incidenceand corresponding y varying angles of reflection. Theplates I5 serve to SlllGld front thereo the rays of-light from'thelens directly in the Although the invention; ShOWIIl in con nection with a casing having twoifllummating faces, it is obvious thatz-it may be equally as advantageously employed in connection i ed f at 1s cla1med 1s: V
